I went here three times while in HK. The place is very authentic, we were the only customers under 50+ years... And this old folk was very friendly.
Waiters don't know much English, but knowing Mandarin helped. There is a set menu which includes soup, rice and dim sum. For dim sum you need to go early, before noon is recommended. If you go too late, you won't get any!
We never looked at the English-Chinese menu, but ate various dim sums and tasted the mock meats from the upstairs counter. Delicious. The a la carte -menu seemed to be moderately expensive, but the set menu is very affordable (only 108-140 HKD for two PAX depending on if it's a weekday or a weekend).
Nice, authentic restaurant for the adventurous. Some basic ability to understand Cantonese/Mandarin helps.Pros: Delicious food, Friendly, authentic atmosphere, Affordable set menus
Cons: Not vegan, Need to know Chinese
